To all 'whom it mafz/ concern.' n

Be it known that I, Lim WnarAMs, a citizen 'of the United States,residing at Texarkana, in the county ofBowie and State of Tekas, haveinvented 'certain new and useful Improvements in Bottle-Closures, ofwhich the followingv is a specification.

Thisl invention is a bottle cap or closure more particularly adapted foruse in connection with milk bottles wherein the cap may be easilyremoved and replaced without ldanger of breaking and is resiliently heldwithout accidental displacement.

@ne object of the invention is to provide a bottle cap kor closure madeof glass 'r porcelain and formed with an overhanging iiange adapted to'coperate with the lips of the mouth of a bottle and is provided with aknob mounted 'on a shank for removing and replacing the cap.

Another object ofthe invention is to provide a cap or closure having ashank and knob with a resilient retaining member formed of wire adaptedto coperat'e with the shank and knob and with the thickened lips of themouth of a bottle.

A-further object of the invention' is to provide 'a proper closure thatwill tend* to keep the lips of the mouth ofa bottle in clean andsanitary condition, one .that will be held on the bottle againstaccidental displacement, one that will be relatively cheap tomanufacture, andnone that may be easily cleansed and sterilized for usea second and more times. y l d, v

Broadly stated the invention comprises a closure including a circular'cap having a disk-like body portion adapted to 4.seat within an annulargroove formed adjacent the mouth `of a bottle, said disk having a tiangeprojecting therefrom and of greater diameter than the disk portion, saidflange being adapted to engage with the pouring edge of the lips whenthe disk portion is seated in the groove, said cap being providedcentrally with an annular recess or groove from the center of whichthere projects upward a shank carrying a knob at its outer end, saidgroove being concentric to the periphery of the fiange, and a resilientholding means formed of wire having a substantially U- shape andconsisting of two wires spaced apart and centrally7 of the transverseportion, said wires being curved and adapted to engage with the shankwhen the wires are separated to pass over the knob, the vertical portionkof the retaining means being curved at their free ends tel approz'imatethe 4curve of the thickened lip of a bottle and also to provide lingerengaging portions to permit the quick removal from said bottle.

Une practical form of construction and assembly will be described andillustrated in the accompanying drawings, in 'which- Figure 1 is adetail sectional view through the bottle and cap but showing the wireretaining means and the knob in elevation,

gig. 2 is a top plan view of the assembly, an

Fig. 3 is an 'end elevation of the cap and the wire retaining meansdetached from a o bottle.

In the preferred: embodiment about to be described the neck 6 of a milkbottle is shown in 'section inFig. 1. The mouth of this bottle isprovided with a thickened lip indicated at 6 and interiorly andconcentric with the lip is a shouldered groove 7 This groove isconcentric to the passage 8 in the neck of the bottle. The shoulderedgroove 7 connects with the pouring edge 9 with a very slightly roundedcorner as more pai'- ticularly shown in Fig. 1.V 4

The bottle closure cmpri'ses a circular cap A that has a disk-like bodyportion 10 that is adapted to seat and be engaged with the shoulderedgroove 7 so as to effect a-closure of the passage 8. Connected with thedisklike portions 10 is a flange 11 that is of greater diameter than thedisk-portion 10. This flange, where it 'joins the disk-like portion 10,forms a shoulder 12 that may be slightly rounded to conform to therounded corner 9 so as to provide for a more effectual sealing of thecontents 0f the bottle.

The flange 11 has one face 13 adapted to rest upon the upper end 14 ofthe lip portion 6 and adjacent the pouring edge orcorner 9. The uppersurface 15 of the flange is provided centrally with an annular recess 16that is of such depth that it partly lies within the body portion 10.Centrally of this recess 16 there arises a shank 17 carrying at itsouter end a knob or button 18.v

This knob or button 18 will provide a linger hold when it is desired toremove the cap A from the mouth of a bottle. The recess 16 will allowthe tips of the ngers and thumb to readily grasp the knob 18.

As shown the cap A may be formed of material similar to that from whichthe bottle is formed but it may be formed of any suitable material suchas porcelain if desired.

Any one of the substances employed in the ceramic art may be used. Itwill be noticed that the under surface 19 is substantially parallel tothe upper surface 15.

To retain the cap A in position upon 'the bottle a resilient retainingmeans generally indicated at B is employed. This retaining meanspreferably comprises an endless piece of wire and formed in such amanner that when bent upon itself it forms the two spaced and parallelportions indicated at C and D. The portions C and D are complemental andare preferably formed to have approximately a U-shape. The transverseportions indicated at 20 and 21 lie substantially parallel again thesurface 15 of the cap and in close engagement therewith. Intermediatethe ends of this transverse portion the wires are bent outward slightlyas at 22 and 23 to provide a loop that is adapted to engage with theshank 17.

As the means is formed of resilient material the members C and D may besprung apart so that they will pass over the knob V18 at the curvedportions 22 and 23 with very little trouble. When the separating forceis removed the two members C and D will springl together and partiallyencircle the shank 17.

The vertical portion of retaining means are similarly formed. Eachvertical yportion comprises a straight section 24 that makes anapproximately right angle bend to the transverse portion and thus liesin close contact with the iiange 11. Extending from this straightsection 24C there is a curved portion 25 that bends inward and isadapted to more or less conformto the curve of the thickened lip 6 asshown more particularly in Fig. 1.

The extreme lower end 26 is bent in a reverse manner and outward awayfrom the neck 5 lof the bottle to provide a finger hold so that when theclosure is placed on a bottle as shown in Fig. 1 the finger may be in-Serted at this point and the closure readily removed from engagement.

From the above description it will be noted that the cap being formed ofmaterial such as glass that it may be readily cleansed and sterilizedfor use a second and more times. It will be noted that the surfaces thatcome in contact with the contents of the bottle and with the pouringedge are surfaces that may be readily washed. As will be seen from Fig.1 when the closure is in position that the pouring edge is effectuallyprevented from contacting with any foreign surfaces so that when thecontents are poured they pass over a clean pouring edge.

When it is desired to remove the cap from the bottle the linger may beinserted under the end 26 which will force the vertical section 24outward so that the curved portion 25 will pass freely over thethickened lip 6. The closure may be then removed entirely from thebottle. When it is desired to remove the cap from the retaining meansthe portions C and D are sprung apart a sufficient distance so that theknob 18 will pass between the curved portions 22 and 23. A reverseoperation will take, place when it is desired to insert a new cap.

A bottle closure comprising a disk having a recess formed in the uppersurface, a shank extending upwardly from the recess and having a knob onthe upper end thereof, the under side of the knob being flat, and means.for securing the closure to a bottle, said means comprising asubstantially inverted U-shaped metal clip formed of a single piece ofwire, the upper cross bar of the clip lying flat upon the top of thedisk and engaged by the lower surface of the knob, the shank being ofsuch length as to leave a space between the upper surface of the diskand under surface of the knob equal to the thickness of the wire clip.

In testimony whereof I affix my signature in presence of two witnesses.
